APPARATUS FOR SOFTENING WATER.

SPECIFICATION forming part of Letters Patent No. 758395, dated April 26,1904.

Kpplication filed June 7; 1901.

T at uihom it may concern/.-

Be it known that I, HAiNOR BREDA, engi-. neer, a subject'of the King ofPrussia, Gerf man Emperor, and a resident of 38. Wilhelmstrasse,-Berlin, Kingdom. of Prussia, German 'Empire,' have invented a new anduseful Ap paratus for Softening Water, of which the following is anexact specification. a

' My invention relates to a new and improved apparatus for softeningboiler-water by add ring small quantities of lime-water and soda to thesame. A

The purpose of the invention is to provide ,an apparatus by means ,otwhich the proportions of lime-water and soda solution added to the waterare automatically regulated, so

that the water treated by means of my new apparatus has always ane'qualsoftness. I at-,

"tain this object by the apparatus illustrated in the accompanyingdrawings, in which situated toward the reservoir a is provided with arecess, so asto form a weir (i over which the water from the channelcflows into the reservoird. The reservoir (Z is provided with apartition 6, which is situated 'so as to divide the water flowingoverthe weir d in -two-parts, the greater part of which flows directlythrough the pipe t into the mixing reservoir at, where. it is .r'nixedwith the lime and soda solutions, while the smaller water" stream isledto the lime-saturate!- f. Before entering the saturater the smallerwater streamis divided in two parts by means of asecond partition g Fig.3. The greater part "of this stream 'flows directly through the pipe itinto the lime-saturater f, while .the smaller" part flowsat first into atilting vessel 0}, by

means of which arrangement it is attained that Berialllm 68,618. momma.)

this part of the water-"stream flows periodically into thelime-saturater-thzit is to say, it flows only at that'time when thetilting vessel is'filled 4 l to a certain height. The water dischargedfrom the tilting vessel flows through a pipe k to the bottom of thelime-saturater f. This lime-saturater consists of a reservoir withcone-shaped bottom, upon .which bottom thevlime to, be dissolved issituated; The whole reservoir is filled with water. Near the upper edgeof the reservoir f a pipe 0 is provided, which leads the saturatedlime-Water. to" the mixing-reservoir a. '-In the middle of the reservoirf two concentric pipes 2 and q are arranged,within which pipesthe pipefor leading the continuous water streaminto the limsat-f -urater issituated. The outer-pipe 0, reaches until over the level of the waterand is provided at its lower end with a funnel s, situated in somedistance. from the-bottom of the reservoir, Theinner pipe q reachesnearlyto'the bottom ofthe reservoir, while the upper end is simatedunderneaththe level of the water. The pipe is, which serves for-leadingthe water discharged from the tilting vessel to the bottom of thereservoir, is situated within the pipe 9. The upper part of the pipe"la-that v is to say, the partup to the level of the water inthereservoir f-will after each discharge fill with air, which air bythesudden discharge of the'water of the tilting vessel will be carriedalong withthis water and pressed through In order to r isprovided,'which leads the airsideward so that the same must rise,outside the pipe q.

part of thewater arises. 'By this circulation,

a thorough solution otthe lime is'insured.

the wholepipe k, so that it leaves this pipe at thebottom of thesaturater, thereby eifect-' -inga stirring up of the lime.

5 avoid this air entering into the pipe 4, a'disk The water above thefunnel f is nearly perfectly quiet and does not stream at'all, sothatthe lime particleswhich are notdissolved can fall to the bottom-aud comein contact again with fresh water.

In order to regulate the addition of soda solution, a valve Z isprovided at the bottom of the reservoir m containing this solution,which valve is connected with the oscillating shaft of the tiltingvessel 2', so that at the same moment at which the contents of thetilting vessel is discharged the valve Z is opened fora moment and asmall quantity of soda solution flows out of the reservoir m into themixingreservoir u. In this mixing-reservoir the mixing of the clearwater entering through the pipe t with the soda solution flowingperiodicaily from the reservoir m into this mixing-reservoir and withthe lime-water entering through the pipe 0 takes place.

By the reservoir 03 being connected to the reservoir to by means of pins(2, sliding on slots (F, the position of this reservoir d can bechanged. By changing the position of this reservoir the position of thepartition 6 will also be changed, thereby changing the proportions ofthe water-stream. If the reservoir d is shifted to the left-hand sidewhen considering the drawings, the quantity of water flowing through thepipe at will be diminished, and consequently the quantity of limewaterwill be increased. At the same time a greater quantity of water willflow into the tilting vessel 2', and in consequence'hereof the periodsbetween the discharging of the tilting vessel will get smaller and arelative greater quantity of soda solution will flow into themixing-reservoir, by this arrangement the quantity of soda solution andof lime-water added to the water to be treated can be exactly adjusted,so as to make the apparatus fit for treating any kind of water.

Having thus fully described the nature of this invention, what I desireto secureby Letters Patent of the United States is 1. In an apparatusfor softening water, the combination of an inlet-reservoir provided withan overflow-weir, with an adjustable reservoir provided with a partitionsituated behind said weir, a mixing-reservoir, a pipe connecting onecompartment of the adjustable 'reservoir with this mixing-reservoir, alimesaturater, a pipe connecting the lime-saturater with themixing-reservoir, and a pipe connecting the other compartment of theadjustable reservoir with the lime -saturater, substantially asdescribed and for the purpose set fort 2.
